A bill currently before parliament that would remove age-based private health insurance (PHI) subsidies for approximately 3.2 million Australians is generating a direct conflict between government projections, commissioned actuarial analysis, and industry modelling – with outcomes that matter significantly for fund pricing, broker retention, and public hospital demand.
The Private Health Insurance Amendment (Modernising the Private Health Insurance Rebate) Bill 2026 was introduced into Parliament by Health Minister Mark Butler on June 25. The bill has yet to pass the Senate. With the Coalition opposing the measure, the government is expected to require support from the Greens and/or other crossbench senators for it to pass. The Senate Community Affairs Legislation Committee is due to report by October 7, 2026. That timetable coincides with the 2027 premium round, with insurers expected to submit premium applications by mid-November 2026 while pricing for the potential membership and claims impacts ahead of the proposed April 1, 2027, commencement.
Under current settings, base-tier policyholders under 65 receive a rebate of 24.118%, compared with 28.139% for those aged 65-69 and 32.158% for those aged 70 and over. The bill removes those higher age-based tiers, so all income groups receive the same rate regardless of age. Speaking at the National Press Club on April 22, Butler framed the measure as a 2004-era policy that was harder to defend in 2026, arguing that subsidising older Australians at a higher rate than younger ones on the same income was inequitable. In his second reading speech to parliament on June 25, Butler confirmed the measure would invest $3 billion in residential aged-care beds, Support at Home packages, and shorter wait times.
The Office of Impact Analysis (OIA) framed the government’s rationale around intergenerational equity: the existing rebate subsidises older Australians more than younger ones at the same income level, even though older Australians are generally unlikely to alter their participation decisions based on the rebate. The OIA assessed the government’s impact analysis as “adequate” rather than “good practice,” noting it would have benefitted from further consultation.
The government’s own projection, stated in parliamentary debate by Butler on July 2, anticipates a change of approximately 44,000 people – or around 0.4% of health insurance membership – exiting the private system. That figure is contested on two fronts. The first is independent actuarial analysis. Finity Consulting, which was engaged by the Australian Government Department of Health and Aged Care to review the effectiveness of the PHI rebate and Medicare Levy Surcharge (MLS), found in its final report that removing the PHI rebate for over-65s would reduce claims funded by private health insurance by $2.3 billion – an amount that exceeds the rebate paid to that group. That finding suggests the government’s fiscal savings estimate materially understates the downstream cost shift to the public system, though Finity’s report predates the specific budget measure and was not modelling the partial reduction now proposed.
The second challenge comes from industry-commissioned modelling. Members Health Fund Alliance has cited actuarial analysis it describes as independent, putting potential Commonwealth savings at around $482 million against approximately $547 million in additional costs shifted onto public hospitals. Unlike the Finity report, this figure is not independently published and originates from Members Health’s own commissioned work.
Members Health puts the effective premium increase at around 9% for affected members – with some facing increases closer to 12% on top of normal annual premium rises – and some older couples facing annual increases exceeding $1,000, in some cases up to $1,600. The government estimates the average impact at around $250 per year. The cost pressure is compounding. The government approved an average premium increase of 4.41% from April 1, 2026 – the highest average increase since 2017 – reflecting rising costs of providing medical and hospital services, which rose 5% in the last financial year.
The health ministers of New South Wales, Queensland, and Tasmania have all formally raised concerns, warning the policy will push more people into an already strained public hospital system. Tasmanian Health Minister Bridget Archer has written to Butler asking him to reconsider, describing it as a cost-shift from the Commonwealth onto the states. That concern is grounded in existing system data. According to the Australian Institute of Health and Welfare (AIHW), half of all patients were admitted from a public hospital elective surgery waiting list within 45 days in 2024-25, with 6% having waited more than a year, and 9.1 million emergency department presentations recorded – up from 7.6 million in 2015-16.
Butler has held firm. “It is, in policy terms, pretty hard to argue with – people should receive the same level of support for their private health insurance according to their income, rather than according to their age,” he told News24. He said the government was “very confident that this is the right thing to do, including by way of the public hospital system,” while rejecting concerns from state governments and the Coalition that the reform could increase pressure on public hospitals.
The commercial implications for brokers are specific and time sensitive. According to the Australian Prudential Regulation Authority's (APRA) December 2025 quarterly statistics, the age group for which the most hospital treatment benefits are paid is 75-79 – the same cohort that recorded the largest gross coverage increase of any age group in that quarter. If price-sensitive members in that high-utilising segment are among the first to exit, the claims impact on funds would extend well beyond lapse volumes alone.
RedBridge polling commissioned by Private Healthcare Australia found that among 1,505 respondents aged 65 and over, 39% said the rebate change would make them more likely to drop their cover – far above the Treasury estimate of 44,000 total exits. Among all respondents, 53% preferred an approach exempting Age Pensioners and low-income older Australians from the reduction, a preference that held across age groups and among 59% of Labor voters.
Meanwhile, the record participation data that framed the week’s news – 12.7 million Australians holding hospital cover as of December 2025, representing 45.6% of the population, per APRA’s annual coverage survey – provides limited forward guidance while the bill and its downstream pricing implications remain unresolved.
